Precision-machined low-profile gas block for .223, 5.56, and .308 bull barrels. Made from 4140 pre-hardened steel with Mil-Spec Manganese Phosphate finish. Gas tube roll pin not included.
The Troy .936 Low Profile Gas Block is purpose-built for shooters running bull barrel rifles that require a 0.936 gas block seat. This component allows you to transition from a fixed front sight gas block to a free-floating rail system while maintaining reliable gas operation.
Gas tube roll pin is not included and must be sourced separately. Verify your barrel's gas block seat diameter before ordering to ensure proper fit. This is an essential component for any bull barrel build seeking to maximize accuracy through free-floating rail systems.
